Starting from Sapporo, the itinerary included Lake Toya, Mt. Usu, the Bear Ranch, Hakodate, and then back to Sapporo via Noboribetsu. The two-day trip was both relaxed and enjoyable. Our guide, Xiao Cai, was incredibly attentive, explaining the sights and recommending great places to buy and eat in Hokkaido. The overall itinerary was comprehensive, and he even accompanied us off the bus to provide explanations and take photos. I've never seen a guide on a 1-2 day tour so dedicated! Thank you, Xiao Cai!
